Passive Sniffing with tcpdump: Essential Commands and Techniques

This video tutorial dives deep into the powerful tcpdump command-line tool, demonstrating essential commands for passive packet sniffing and network analysis. Learn how to capture, filter, and analyze network traffic using practical examples. Explore techniques for capturing from specific interfaces, limiting packet counts, saving captures to files, and filtering by protocol (TCP, ICMP), host, source, destination, and port. Whether you're a network administrator, security professional, or simply curious about network traffic, gain the knowledge to effectively use tcpdump for passive network monitoring. The 23-minute guide includes a reference to a complementary video on ARP Spoofing for active sniffing techniques.
